To all whom it may concern:

Be it known that L'JAMns A. PARENT, a citizen of the UnitedStates ofAmerica, residin at Detroit, in the county of Wayne and btate ofMichigan, have invented certain new and useful Improvements in Gas-Pressure-Reducing Devices,, of which the following is a specification,reference being had therein to the accompanying drawings. This inventionrelates to a gas regulating device commonly known as a V gas saver,

and the primary object of my invention is to furnish agas pipe or otherconduit with a novel form of bafl'le which will tend to retard thevelocity of gas therethrough and consequently reduce the pressuretosuclija degree as to produce a savlng'of gas and better ignition at aburner.

Another ob ect ofm I 1nvent1on-'1s to prov1de a gas conduit with aseries of articulated baffles providing a tortuous or sinuous passagefor gas 1n the conduit, the baflles bein d1s .osed so as to revent ex- Dcess ve pressure at an outlet, and in consequence of such baffles-1t 1simpossible for gas to flow throu h meters and 1nto burners at r agreater rate than can be recorded or used.

In the first instance, it-is-possible to provide a desired number ofbaffles to reduce pressure of gas a desired degree whereby a meter oflimited capacity could be installed on a high pressure gas line. In thesecond instance, it is a well known factthatvarious types of burnerscannot be adjusted for excessive gas pressures, so my bafiles may beinstalled to properly regulate the pressure of gas for a burner so as toinsure proper combustion at the burner.

'A further object of my invention is to provide fluid bafiies forconduits with the baffles constructed to insure a thorough c0m-'mingling of the products of combustion, and also to prevent displacementof the baffles by gas pressure within the conduit.

The above and other objects are attained by a mechanical constructionthat will be hereinafter specifically described and then claimed, andreference will now be had to the drawings, wherein- Figure 1 is alongitudinal sectional view of a gas conduit provided with baflies whichcooperate in producing a unitary result;

Fig. 2 is a cross sectional view taken on the line II-II of Fig. 1; 1 r

I Fig. 3 is a perspective iew of'an initial or conical pressure reducingmember, and 1 Fig.4'is a perspective view of a secondary or diskpressure reducing member Assho'wing a conventional form of gas conduit,the reference numeral 1 denotes" a pipe having one end thereof connectedby a sleeve t a j e P pe 3, and the opposite end f. th pipe 1 hasconven: V v

tionalform of union connection t with a pipe 5: The connections orcoupl1ngs2'an'd 1 permit of the'pressure, reducing member Specificationof Letters fatent. Paigght ed; lvlay being-easily installed within thepipe 1, and reference will'first be-had to'the initial pressure reducingmember associated withthe coupling & andshown in Fig.3. The

initial pressure reducing membercomprisesa cone 6 havlng tsjlarge endprovi'dedwithj a peripheral flange 7 and this flange may be seatedagainst the end of the pipe 1',within"' the coupli'n'g l, with the smallend 'o'f the cone 6 extending into the pipe; The flange 7"will preventthe pressure of -gas-from shiftinga conewithinthe-pipe 1, andwhen f' thegas impinges against the converging wall-s of the cone the gas is moreor less baiiied' so that its flow is somewhat retarded and {its pressurereduced; 2 Mounted in the 1 large end of the cone 6 and axially thereofis a small cone 8 which is supported by opposed arms 9 having the endsthereof solfrom the cone 6 by having its innerend completely closed sothat said cone will provide a pocket and positive baffle for gas entering the same. When the gas is retarded by the cone 8, it will benecessary forthe gas to flow over the edges of the cone to enter thecone 6 and the restriction or reduced passagebetween the cones 6 and 8is sufiicient to further retardthe gas as it enters the large cone orconical member .6.

dered' or otherwise connected to the walls of the cones 6 and 8. Thecone 8 differs The'secondary pressure reducing'member comprises a seriesof spaced d1sks 10 have ing diametrically opposed edges thereof notched,as at 11, to receive parallel arms 12 which may be soldered or otherwisefixed relative to the disk so that the same will be maintained in spacedrelation. Ends of the arms 12 may be bent, as at 13 so as to form lugswhich may be anchored between the ends of the pipes 1 and 3, within thesleeveor coupling 2 and with the arms so held it is practicallyimpossible for gas impinging against the disk to dislodge the memberwithin the pipe 1.

The peripheral edges 10 of thedisk are notched or cut away, as at 14 andone side wall of each notch bent outwardly from the plane of the disk toform a deflector 15, With each disk having a single notch and dfiectorandno two notches in longitudinal alinement, it is obvious that gas musttravel in a sinuous path through the pipe 1 and when encountering thedeflectorsol5 a whirling motion will be imparted to the gas tending tofurther retard its passage through the chambers formed between the disk10 within the pipe 1. The gas in seeking its passage through thesecondary pressure reduc ing member will have its pressure reduced andwhen this secondary pressure reducing member is associated with theinitial or conical pressure reducing member previously described, itispractically impossible for an excessive pressure of gas to pass throughthe pipe 1 and consequently there will be a saving of gas and betterignition regardless of the nature of gas passing through the pipe. Asnatural gas is more active or volatile than artificial gas it may beonly necessary to increase the number of disks 10 to compensate for theactivity of the gas.

Under some conditions it may be only necessary to use the initial gaspressure reducing member, or even the secondary pressure reducing memberby itself, but the best results have been attained by using the membersas shown in Fig. 1. Both of the pressure re ducing members may be madeoflight and durable metal that will not corrode or deteriorate due toany moisture within the gas,

and since no alterations are required whatsoever in the conduit, it isobvious that the members may be easily and quickly installed. I wouldhave it understood-that the size and shape of the pressure reducingmembers may be varied, and that any desired number of said members maybe employed to attain a desired reduction in gas pressure.

lVhat I claim is 1. Means for reducing gas pressure within a conduitcomposed of joined pipes, comprising parallel arms having end lugsclamped betweentlie joined pipe ends of said conduit, and a series ofdisks carried by said arms and having notched edges with some of saidnotches accommodating said arms and other of said notches providing atortuous passage from one disk to another.

2. The combination with aconduit composed of joined pipes adapted tohave gas pass therethrough, of a cone open at one end only and supportedaxially of said conduit and providing a baflie, a cone surrounding andsupporting the first mentioned cone, adapted to receive gas therefromand restrict the passage of gas to the axis of said conduit, a series ofdisks within the conduit adjacent the last mentioned cone causing thegas to travel in a tortuous path impinging against the walls of theconduit, and means between joined pipe ends of said conduit preventinglongitudinal displacement of said disks.

In testimony whereof I afiix my signature in the presence of twowitnesses.
